/**
 * <p>
 * FieldVerifier validates that the name the user enters is valid.
 * </p>
 * <p>
 * This class is in the <code>shared</code> package because we use it in both
 * the client code and on the server. On the client, we verify that the name
 * is valid before sending an RPC request so the user doesn't have to wait for
 * a network round trip to get feedback. On the server, we verify that the
 * name is correct to ensure that the input is correct regardless of where the
 * RPC originates.
 * </p>
 * <p>
 * When creating a class that is used on both the client and the server, be
 * sure that all code is translatable and does not use native JavaScript. Code
 * that is not translatable (such as code that interacts with a database or
 * the file system) cannot be compiled into client side JavaScript. Code that
 * uses native JavaScript (such as Widgets) cannot be run on the server.
 * </p>
